Abstract (en)

[origin: WO0136886A1] The invention concerns a method for cryogenic cooling of products (P) which consists in causing the products to pass through a cryogenic tunnel (1) provided with inlets (Li/Ri) for a cryogenic liquid and means (Mi) for generating convection of the atmosphere inside the tunnel, wherein products of different dimensions (Ci) are treated, in the following manner: if at any given time, the tunnel processes a product of dimension Cx, all or part of the cryogenic liquid inlets and convection generating means are in operation, and a product of dimension Cy subsequently enters the tunnel, for the period during which products of dimensions Cx and Cy coexist in the tunnel, an intermediate operating mode is adopted whereby, depending on the Cy/Cx ratio, some of said means and/or said cryogenic liquid inlets are re-activated or deactivated.
